Police raided a Copeland Street apartment after an investigation into a suspected fentanyl trafficking ring.

QUINCY – Five people were arrested when police raided a Copeland Street apartment they said is part of a fentanyl trafficking ring.

Police served a search warrant at 338 Copeland St. at 10:45 a.m. Tuesday, after an investigation into drug dealing at an apartment in the building.

“The arrests were for trafficking. That’s all the information I have at this time,” Sgt. Karyn Barkas said.

Police were still booking the suspects at 2 p.m. and could not release their names.

Barkas said more information on the investigation would be available later this afternoon.

Police departments are cracking down on fentanyl dealers, as the drug has been blamed for the near-exponential rise in opioid overdose deaths over the last decade. The synthetic opioid is 50 to 100 times stronger than street heroin and was responsible for 75 percent of the opioid-related deaths last year, where toxicology screens were available, according to the state Department of Health.
